Characterization device and computer program thereof

Abstract

A characterization device capable of extracting the characteristic values of high-reliability hard macros at high speed. A characteristic value extraction unit calculates the delay time at measurement points within the hard macro and extracts the characteristic values by applying a slew to the signal waveform that is inputted to the hard macro and making a static path search. A dynamic verification unit verifies whether the characteristic values are adequate or not by carrying out a dynamic verification of the hard macro utilizing the characteristic values extracted by the characteristic value extraction unit. The characterization device can therefore shorten the time required to make a dynamic verification, and further is capable of extracting the characteristic values of high-reliability hard macros at high-speed.
